(forgot to CC LKML) The options,
CONFIG_CFAG12864B=y CONFIG_CFAG12864B_RATE=20 causes a crash at boot in 2.6.20-rc3-mm1. I don't have the hardware associated with the options. It looks like it just doesn't have guards to detect if the hardware doesn't exists. Here is the crash, ks0108: ERROR: parport didn't find 888 port BUG: unable to handle kernel NULL pointer dereference at virtual address 0000004 printing eip: c02dbff9 *pde = 00000000 Oops: 0000 [#1] PREEMPT SMP last sysfs file: Modules linked in: CPU: 3 EIP: 0060:[<c02dbff9>] Not tainted VLI EFLAGS: 00010246 (2.6.20-rc3-mm1 #11) EIP is at ks0108_writecontrol+0x79/0xc0 eax: 00001008 ebx: 0000000a ecx: 673e2eb8 edx: 00000001 esi: 0000000a edi: 00000000 ebp: f7c3ff6c esp: f7c3ff50 ds: 007b es: 007b fs: 00d8 gs: 0000 ss: 0068 Process swapper (pid: 1, ti=f7c3e000 task=f7c26a90 task.ti=f7c3e000) Stack: 00000001 f7552c40 f7c3ff60 c0120e3f 00000000 c049f450 00000000 f7c3ff74 c02dc159 f7c3ff80 c02dc177 00000000 f7c3ff98 c048feda 00000378 c02d74db 00000000 00000000 f7c3ffe0 c0478610 c03d9d35 00000004 f7c26a90 c0473fc4 Call Trace: [<c01053da>] show_trace_log_lvl+0x1a/0x30 [<c0105499>] show_stack_log_lvl+0xa9/0xd0 [<c01056c7>] show_registers+0x207/0x370 [<c0105949>] die+0x119/0x250 [<c011d267>] do_page_fault+0x277/0x610 [<c038e9d4>] error_code+0x7c/0x84 [<c02dc159>] cfag12864b_e+0x19/0x20 [<c02dc177>] cfag12864b_page+0x17/0x30 [<c048feda>] cfag12864b_init+0x8a/0x130 [<c0478610>] init+0x110/0x250 [<c0104fd3>] kernel_thread_helper+0x7/0x14 ======================= Code: 8b 98 ec 00 00 00 0f b6 03 24 df 88 45 f3 80 75 f3 20 0f b6 43 01 20 45 f EIP: [<c02dbff9>] ks0108_writecontrol+0x79/0xc0 SS:ESP 0068:f7c3ff50 <0>Kernel panic - not syncing: Attempted to kill init! - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
